Subtitles

Subtitles made on the phone, on demand (the viewer's CC button): the video's sound in 30 s windows, the one being watched first, then onward, then from the start; in each, only the speech (SpeechDetector) is transcribed (Whistle) and its words grouped into short lines. Saved per video version, so watching again is instant.
